Title: Evaluating method for semiconductor
Inventor: TERAJIMA KAZUTAKA
IPC: H01L21/66
Filed: 1978-12-16
Abstract: PURPOSE: To easily measure the minute distribution of impurities or crystal defects of a wafer without damaging it, by scanning a light beam over the surface of the wafer to determine a lifetime.  
     CONSTITUTION: An electric field is applied to a single crystal of InSb cooled at 77°K. CO 2  laser light of 10.6μm in wavelength is irradiated as pulses upon single crystal. At that time, an electrical current flowing in the single crystal shows an attenuating property. The curve of the attenuation is represented by a formula I=I 0 exp(-t/τ) where τ denotes the lifetime of carriers. The lifetime can be determined by measuring the time when the value of I 0  becomes 1/e. The lifetime relates to the carrier density in the single crystal of InSb. The carrier density of a minute part irradiated with the laser light can be measured in terms of the lifetime determined from a characteristic diagram of R. A. Laff.

Title: Rotary volumetric type fuel pump for automobile
Inventor: YAMAZAKI SATORU
IPC: F04C15/00
Filed: 1981-10-05
Abstract: PURPOSE:To prevent the corrosion of a motor due to the leakage of a fuel and to avoid the danger of the leaking fuel being ignited by a method wherein in the case of a  roller vane pump, a synthetic resin rotor containing magnetic particles and supported  by a projection formed on a partition wall is driven by a magnetic member fixed to the output shaft of the motor through the partition wall. CONSTITUTION:The disk-shaped magnetic member 1b made of a magnetic material such as a ferrite magnet and magnetized to a single pole or a plurality of poles in the circumferential direction is fitted on the top end of the output shaft 1a of the motor so  as to extend normal to the axis of the output shaft. Further, the rotor 4 is rotatably  supported by the projection 2a and is provided with a plurality of equally spaced  grooves 4a opening in the circumferential direction. In this case, the rotor 4 is produced by molding a synthetic resin material containing the magnetic particles and is  magnetized to a single pole or a plurality of poles in the circumferential direction.  Thus, when the magnetic member 1b on the top end of the output shaft 1a of the  motor is rotated with the rotation of the motor, the rotor 4 of the roller vane pump  rotates due to its magnetic force and the fuel flows through a pump chamber only  without entering into the motor section at all.

Title: Saw blade
Inventor: NAKAHARA KATSUMI
IPC: B23D61/12
Filed: 1992-06-18
Abstract: PURPOSE:To perform effective curling of a chip produced by a saw tooth having a high depth of cut and a high tooth height by bringing inclination of the chip induction surface of the saw tooth having a high tooth height into a comparatively steep state. CONSTITUTION:Inclination of the chip induction surface 15 of each of saw teeth 3, 7R, and 9L with a high tooth height is brought into a steep state. This constitution causes effective curling of a chip 27 produced by the saw teeth 3, 7R, and 9L having a high depth of cut and a high tooth height. Reversely, inclination of the chip induction surface 21 of saw teeth 5L and 11R having a low tooth height is brought into a gentle state. This constitution causes effective curling of a chip 29 produced by the saw teeth 5L and 11R having a low depth of cut and a low tooth height. As a result, production of chips exercising an adverse influence on a saw blade on a whole is reduced, an increased life for a saw blade is provided, and chip disposal after cutting is simplified.

Title: Delivering device for article
Inventor: SHIAKU TAMOTSU
IPC: B65G1/04
Filed: 1987-06-26
Abstract: PURPOSE:To simplify the structure and miniaturize a device by linking a movement transmitting system for linearly reciprocating a drawer to a movement transmitting system for engaging/disengaging a hook. CONSTITUTION:As a motor is driven moving a movable chain 25, a movable lever 32 is also rotated in the arrow direction, rotating a lower sprocket 40. Then, a chain 44 is moved to rotate an upper sprocket 42. Thereby, a first gear 43 is 90 deg. rotated counterclockwise by the ratio of the diameters of the upper and lower sprockets 40, 42. Hence, a second gear 47 is 90 deg. rotated causing a hook 49 to be engaged with the handle 4 of an article 3. At the same time, the rotation of the gear 43 advances an upper hook 52 in the direction of the article 3 via the movement of a rack 48, to prevent the floating up of the article 3 with the upper hook 52. As the motor is further rotated, the lever 32 with its pin 33 kept downside is laterally moved, moving the article 3 via the lateral movement of a drawer 22. Thereby, the structure can be simplified while miniaturizing a device.

CONSTITUTION:A passage 9 inclined in the direction of a resultant force, consisting of the opposite direction to an air flow and the flowing direction of a refrigernat, is provided in the nearly center part of the overall length of a flat tube 1, piercing through the wall 7 of each refrigerant pipe, and a bar stock 11 with a spiral guide 10 around it is inserted in the passage 9. Although a refrigerant near the inlet side A of an air flow is completely heat-exchanged, a refrigerant 6 near the outlet side B of an air flow is not fully heat-exchanged. But the temperature in an evaporator can be made uniform because the refrigerant 6 near the outlet side B of an air flow is fed to the parts of refrigerant pipes close to the inlet side A of an air flow as shown by an arrow sign 12 along the bar stock 11 provided nearly in the center part of the overall length of a flat tube 1.
